Designed between late 1943/44 the single jet
engined twin-boom fighter most novel feature was the use of jet and rocket
power, this allowed the aircraft to reduce it's take off run and also enabled
it to reduce engagement times. By the autumn of 1944 the P.IIV was very
well advanced in development with some subassemblies being completed ready
for the first prototype, but the maximum speed of the aircraft was to low
and it used to many "premium materials" in it's design, the cost of modifying
the completed aircraft to solve these problems in time and money was just
to much. Focke-Wulf had no other option but to scrap the whole "Flitzer"
program.
